Detailed Description for TL431CZT
Product Overview
The TL431CZT from STMicroelectronics is a through-hole shunt voltage reference IC with an adjustable output. It provides a minimum/fixed output of 2.495V and a maximum output voltage of 36 V, with a specified output current of 100 mA. The device is housed in a TO-226-3, TO-92-3 (TO-226AA) package and has a tolerance of ±2.21%, for circuit designs requiring a defined shunt reference point within the specified voltage and current limits.
Key Features
- Adjustable shunt voltage reference output with 2.495V minimum/fixed value
- Maximum output voltage rating of 36 V
- Output current capability of 100 mA
- Tolerance of ±2.21%
- Cathode current of 1 mA
- Operating temperature range of 0°C ~ 70°C (TA)
- Through-hole mounting in a TO-226-3, TO-92-3 (TO-226AA) package
Applications
- Analog measurement circuits requiring an adjustable shunt reference voltage
- Comparator or threshold-setting circuits where a defined reference point is needed
- Power supply control and regulation circuits using a shunt reference for feedback or biasing
- Data conversion and signal-conditioning circuitry needing a defined reference voltage
Design & Procurement Notes
Because the device is through-hole mounted in a TO-226-3, TO-92-3 (TO-226AA) package, PCB layout and mechanical clearance should account for the package form. The 2.495V minimum/fixed output, 36 V maximum output, 100 mA output current, and 1 mA cathode current should be considered when selecting external biasing or load components. The ±2.21% tolerance and 0°C ~ 70°C (TA) operating temperature should be considered when evaluating reference accuracy and ambient operating conditions. Thermal and ambient conditions within the 0°C ~ 70°C (TA) range should be considered during circuit layout and enclosure selection.
